' MOTOR- PLOW.

noiae'se.

To all whom it may concern Be it known that I, DANIEL B. HILL, a

citizen of the United: States, and residentof Grayville, \Vhite county,Illinois, have invented certain new and useful Improvements inMotor-Flows, of which the followto the accompanying drawings, forming apart hereof.

My invention relates to improvements in motor plows and, is especiallydirected to that class of plows which are knownas gang plows and aredriven and steered by a motor carried by the frame thereof.

The primary object of my invention is to construct a frame, for carryinga number of plows, havmg'cut away portions which permit of the turningof the whole structure in a minimum of space.

A further object of my invention isto construct a plow of this class inwhich the propelling and steering is accomplished by the employment of amotorcarried by the plow frame.

For the above purposes my invention con sists in certain novel featuresof construction and arrangements of parts as will be hereinafter morefully described, pointed out in the claims-and illustrated by theaccompanying drawings, in which:

Figure 1 is aplan of the plow, the operators platform and cab beingremoved; Fig.

2 is anelevationj-of the complete plow; Fig. 3 1s a transverse,vertical, sectional elevation taken approximately on the. line 3+3 ofFig. 1; Fig; 4 is an enlarged, detail, sec

tional elevation taken on the line H of Fig. 1; Fig. 5 is a detail planpartly in section illustrating the means wherebyfthe plow may besteeredeither'by' hand or by the 'motor; Fig. 6 is a vertical, sectionalelevation taken on the line of Fig. Referring by numerals to theaccompanying drawings: 1 designates the frame proper which is.substantially rhomboidal' and at'feach of its side margins is providedwith a semicircular portion 2, the semicircular portion, at'the righthancLside of the frame, being in advance of the left hand semicircle,and at the forward end of the frameithere is an extension 3..

1' and 5- designate the supporting and driving wheels which are of anyordinary construction and each of which, carries a bevel gear wheel 6;For connecting the Specification of Letters Patent.

wheels l and 5 with the frame there are the bear ng plates 7 whichproject laterally g Patented Mar. 5 ,1912. Application filed May 9,1910. Serial is. 560,194.

wheels 9, each of which is interiorly ,1

threaded for the engagement with andsupporting of the threaded uprights10. Con-- nected with and preferably formed integral with the threadeduprights 10 are thebifurcated members 11 which embrace the bearingblocks 12 for the stub shafts 13 which support the wheels 4 and 5.

As shown, each of the housings 8 incloses a worm lanormally inengagement with the gear wheels 9, and 15 designates cranks for themoving of said worms for the turning of the gear wheels 9 to raise andlower the frame over the threaded uprigl'its 10. For supporting the rearend of the frame there isa caster wheel 16 rotatably carried on a stem17. Arranged at'the apex ofthe frame at its rear end there is a housing18, which housing is provided with integral wings 19 for attachment tothe frame 1. The housing incloses a rectangular sleeve 20 having on itsforward face teeth forming a rack 21- which sleeve embraces the stem 17and is adjust-ably secured vertically relative the stenrby means of thecollars 22. Arranged withm the housing 18 1s a gear wheel 23 mountedupon ai'shaft 2% which extends through the housing, and carried by ashaft within the housing and not shown is a gear and worm connectionwith the shaft 24 manually operable by a. crank 28. ,By this" means ther'earmost end of the frame may be raised or lowered as the forward endis raised or lowered over the threaded up rights 10, as required fordifferent depths of plowing, but which means I did not claim in thisapplication.

For driving the Wheels 1 and 5 there is a, motor 29 preferably agasolene engine which is carried by the extension 3 of the frame. with aradiator 30 of ordinary construction, the connections between the motorand radiator being not shown. Carried by the Themotor as shown isprovided frame 1 is a transmission gearing box'31 which is of ordinaryconstruction and is connected with the engine shaft 32 inan ordinarymanner. Extending from the transmission gearing box to a point adjacentthe right hand side of the machihe frameis a shaft 33having on its endop 40 with a locking member on theengine shaft-- posite the box a bevelgear Wheel 34 which meshes with a gear wheel 35 carried on a shaft. 36arranged at right angles and beyond the shaft 33.

' Extended vertically from the plates 7 are the bearing blocks 37 andintermediate in the ends of the bifurcated members 11' and at theirupper ends are supported by bearings 43 formed integral with-the bearingblocks 37. Each of the wheels 41 is feathered to a shaft 42.

' shafts 42 are the bevel gear wheels 44 secured against rotationrelative the shaft and arranged to mesh with the bevel gear wheels 6carried by the' guide wheels 4 and 5.

' To impart motion to the shaft'39 there is a sprocket wheel 45embracing the shaft 39 and a sprocket wheel '46 carriedby the shaft 36and these two sprocket wheels are connectedby the chain 47., Thus, asthe engine is operating, the motion therefrom, through the transmissiongearing not shown), rotates the shaft 33 ,which through the me dium ofthe gear, wheels 34 and 35, sprocket wheels 46 and 45 and chain 47motion isim-' parted to the shaft 39. As the shaft 39 is rotated thedriving wheels 4 and .5 are driven through the medium of the bevel g arWheels 40, 41, 44'and 6'. Itis to be understood in this connection thatthe transmis v sion gearing is provided with the' usual means forreversing its movement -well as to throw a clutch into or outfof'en'gagement as required,and all of which is not shown for the reasonthat any common form.0

such means may be employed.

Tw'o vforms'of steering devices are employed, one. of which is operatedsolely by 4 hand and the other arranged to be operated by the motor. V

The means whereby the machine may be steered manually comprises apost-48 which is arranged about centrally of the frame of the machine,at the top of which is fixed an ordinary hand wheel 49'and at oradjacent the bottom of the post is a worm 50 which is keyedor otherwisesecured to the shaft. The post is maintained in a, verticalposition bymeans of bearings'51 carried by a housing 52. Extended through thehousing is a horizontal shaft 53 upon which is a worm wheel 54 in meshwith the worm 50. Secured to the shaft 53 and extending downwardly atright angles to the shaft is a lever '55. Extending rearwardly from eachof the shafts42 beneath the bearing blocks 12 for the stub shafts 13 isan arm 56 which.

Carried by the arms are connected with a rod 57. Pivotally connectingthe arm 56 with the lever 55 and actuated by the steering post isconnecting rod 58. By the means just described the two main driving andsupporting wheels are moved to steer the frame by a manipulation of thehand wheel 49. v

vFor the steering of the caster wheel 16 simultaneously with thesteering of the wheels 4 and 5 I have provided an arm 59 extendedlaterally from the stem 17, and

carried by the frame of the machine is a bell-crank lever 60 and.pivotally connected with one end of the lever 60 and with the arm 59 isa rod 61-. The oppositeend of the bell-crank lever 60 is connected withthe arm56 by the 1Od62. Thus,'as the machine is steered, the variousconnecting devices operate the drive wheels in opposite directionsrelative the caster wheels. By rea- .'son of the bearings 37 and 38 theshaft 39 is supported in planes wholly above the drive wheels so thatthe drive wheels may operate beneath said shaft.

For connecting the steering apparatus so that it may be operated by themotor I have provided a bevel gear wheel 63 on the transmission gearshaft 33. Supported on a shaft carried in bearings 64 pendant from .theframe ofthe machine there'is a shaft '65which' carries a bevel gearwheel 66 meshing'with th'cgear wheel 63. Keyed or otherwise securedtothe shaft 65 i's'a pair of connected ffriction disks 67 Supported in ahearing 68, which is arranged between the frfetion disks 67, is'a shaft69 and keyed or otherwisesecured to the shaft 69 is a friction.disk 70arranged-for engagement with eitherione of the disks 67. The shaft 69 isextended through slots -71 formed in the alls oftgli'e' housing 52.-Embracing the shaft within.thelhoi 1sing is a worm 7 2 arrangedffdr-en'gag ement with the worm 50 carried by'the steering post. 'Thebearing 68 justreferred to i's*clearly'shown in Fig.

6 and is of the type which permits slight lateral play-of the entireshaft 69.

For normally holding the worm 72 out of engagement with the worm 50 ofthe steering post there is a collar 7 3'to which is connected acontractile coil spring 74.

For moving the shaft 69 to place the worm 72 in mesh with the worm 50 ofthe steering post there is a bell-crank lever 7 5 carried by a bearing76 projecting down wardly from the frame 1. One arm of the lever 7 3 isconnected with the collar 73 by means of the link 77 and the other armof the lever 75 is connected with a foot lever. not shown, by means ofthe link 79.

For varying the speed of the steering device the disk 70may be movedtoward or away from the centers of the disks 67 by means of thebellrerank lever 80, one end 'of which is bifurcated and arranged toengage a pin 81 carriedby an integral part of the disk 70, the other endof the lever 80 is connected with a rod. 82 which is connected withanylsuitable operating lever (not shown For controlling the direction ofthe steering means the dlsks 67 are movablelengthwise relatively theshaft 65 so that they will engage atdi'fterent times, opposite'sides' ofthe periphery of the disk 70. For moving 1 the disks 67 as abovedescribed there is a bell-crank lever 83, one end. of'which isbifurcated to straddle a pin 84 carried by an integral part of the disks6'? and to the 90p posite end of'the lever 83 is a rod 85 connected witha hand lever,- not shown, provided with a pawl and segmental rack forholding the disks 67 in various set positions.

' cording to the-connection made between the I by the transmissiongearingnot shown in engine and transmissiongearing shaft 33 detail. Fromthe shaft 33 motion is imparted to the drive shaft 39 through the bevelgear wheels 34 and 35 and the sprocket gearing 45, 46 and 47. From theshaft 39 motion is imparted to the drive wheels through the medium ofthe bevel gears 40, 41 and the bevel gears 44 which mesh with and rotatethe bevel gears 6 carried by the drive Wheels, By reason of thelocationof the shaft 39 in a plane some considerable distance above themachine frame proper the-wheels 4 and 5 may operate beneath said shaftas required in steering the machine. As previously stated, the machineis normally in condition to be steered manually by means of the handWheel 49 which rigidly connected with the steering post 48. As the handwheel is turned in eithe' direction, to the right or left, the wheels 4and 5 and caster wheel 16 are turned through the medium of the levers 56for the wheels 4 and 5 and lever 59 for the caster wheel, which leversare connected :by suitable rods with the steering post. By thisarrangement the wheels 4 and '5 are simultaneimsly turned in/ the samedirection while the caster wheel ,is turned in an'opposite direction,thereby causing the entire machine to be turned completely about in amiuinuim of space, as the wheels 4' andfi operate in the cut awztyportions in thesides of the frame. f

If, for any reason, 'the manual steering is diflicult or cannot lfeaccomplished .in the required time the operator may connect the steeringapparatus with the motor so that the steering may be accomplished by.the

motor. When the machine is steered by the motor the operator can directthe course of travel of the machine by. the moving of the friction disks67. By moving one of the disks to engage with a cotiperating disk themachine is directed to travel to the right and by moving the said diskaway from the cooperating disk andplacing the opposite disk 67 to engagewith the coiiperating disk the machine is directed to travel tothe left.

The speed of the steering device may .be controlled by moving saidcooperating disk to- Ward or away from the centers of. said disks 67.

By means of the threaded uprights 10 and the worms 14 the wheels 4 and 5may be, if desired, vertically adjusted independently of each other, asrequired for causing one wheel to ride over the land and another wheelto ride in a furrow or vice versa, or

for leveling the entire machine to travel evenly over differentialinclined lands.

I claim: 1. In a machine of the class described, a substantially,rhomboidal frame, a substantially semicircular cut away portion in eachside margin of the frame, one in advance of the other, a steering wheel,located for movements when steering, in each of said cut away portions,a wheeled support for the rear end of said frame, connections betweenall of said wheels where the first mentioned wheels may be turned i thesame direction and the wheelednsup t for the rear of the frame turned inan opposite direction, manually perated means for steering all of said weels, a motor, and means for connecting sa dmotor with said manu- I allyoperated steel 'ng means at times.
